Description

Technical Field

[0001] The present invention belongs to the field of arthroscopic surgical medical devices, and particularly relates to an arthroscopic surgical guiding channel device. Background Art

[0002] Arthroscopic surgery is to insert a lens metal tube with a lighting device into the joint cavity through a very small incision. Modern medical research has found that the root cause of bone and joint diseases lies in the loss of the protective ability of the "joint protection system" such as cartilage. Currently, most diagnostic and treatment methods use arthroscopes, that is, arthroscopic surgery. Arthroscopic surgery is to insert an arthroscope through a guiding channel, extend it into the joint cavity, transmit the internal structure of the joint cavity to a display screen, observe the pathological conditions and locations in the joint cavity, and at the same time conduct a comprehensive examination and clean up the diseased areas under television monitoring.

[0003] Currently, for the creation of an arthroscopic guiding channel, a device that uses a cruciate ligament locator and an anterior cruciate point locator in cooperation is basically adopted. This device can quickly create an arthroscopic guiding channel during the operation. However, such a device still has great limitations in the creation of an arthroscopic guiding channel. After the anterior cruciate point locator is inserted into the joint and fixed, the cooperating cruciate ligament locator can only create an arthroscopic guiding channel in a fixed direction and cannot create channels in multiple directions. For the left and right knee joints, this device cannot be used interchangeably on the left and right, making its use cumbersome and troublesome. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention designs an arthroscopic surgical guiding device. In this device, the traditional anterior cruciate point locator is decomposed into two sections. The front section is used to penetrate deep into the joint to provide a fulcrum for the whole device, and the rear section cooperates with the cruciate ligament locator. The two sections are connected by a universal joint. When the front section is fixed, the rear section can complete the up-and-down and left-and-right rotation movements with the universal joint as the fulcrum through the universal joint, facilitating the search for the best positioning point of the arthroscopic guiding channel. At the same time, the rear section is movably connected to the universal joint, and the two can rotate relative to each other. Through the cooperation with the universal joint, the rear section can adjust its position in multiple directions. The rear section rotates in three directions relative to the front section. When the front section is fixed, the rear section can cover all positions around the joint. During the operation, an arthroscopic channel can be created at multiple points without moving the front section, and the positions of joint diseases can be observed at multiple points, improving the surgical efficiency and quality. At the same time, the device is also equipped with a single guiding tube for creating an arthroscopic guiding channel. This guiding tube can directly create an arthroscopic guiding channel for the patient's joint without the help of other auxiliary tools. It is inserted into the joint from one end at one angle and exits from the other end at another angle, and the angle can be freely adjusted according to requirements, and it can adapt to the creation of arthroscopic guiding channels for various joint parts and various complex situations.
